Air Quality

by

Air quality affects all drivers no matter where we are.  Many decades ago, people began to become more aware of how air pollution negatively affects our health.  But have you ever thought about the air quality inside your vehicle?

Cabin air filters are now coming standard on most new vehicles since the 2000 model year.  These filters clean the air in the passenger compartment, so the poor air quality outside your vehicle doesn’t come inside.

They can filter particles down to three microns…that’s good enough to clean out dust, pollen and most air pollutants.  If you suffer from allergies, this is certainly good news, but even if you don’t, this is still a good thing.

You can look in your owner’s manual to see if you have a cabin air filter.  If you do, there will be a recommendation for replacing it when it gets dirty.  If you live where there’s a lot of dust, pollen or pollution,  you may need to change it more often than recommended.  You can also ask your Express Car Care service adviser.

The difficulty of changing a cabin air filter depends on your vehicle.  Some are quite accessible, others can take some time getting to them.  They’re usually located in the engine compartment or under the dashboard.

Because cabin air filters are somewhat new on the scene, some drivers haven’t heard of them – even people who have cabin air filters in their vehicles.  Express Car Care service advisers report customers complaining of an unpleasant odor in their vehicle and it usually turned out to be a dirty cabin air filter.

An important note for hybrid owners:  there’s a special air filter that cleans the air that cools the hybrid battery pack.  This filter should be inspected every time the cabin air filter is inspected and replaced.  If this filter gets dirty then the battery pack can overheat.

Have You Overlooked These Car Maintenance Problems?

Outside of your housing costs, your vehicle is probably your second biggest expense. A recent study showed that the average loan for a new car was $31,099, with an average monthly payment of $515.

Think used cars are a better deal? Even used car purchases average $21,375, with a payment per month of $398.

That’s a lot of money flowing out each month.

If you keep your vehicle in good shape, you can minimize additional expenses to keep your car running. But without a car maintenance plan in place, you’ll experience problems soon after you drive it home for the first time.Have You Overlooked These Car Maintenance Problems?

What does it take to create an effective plan? What does it take to avoid car maintenance problems and ensure your car is ready whenever you are? Put these basic tasks into your schedule to keep your car running its best all year long.

Wash Your Car

It almost sounds too simple, doesn’t it? How can washing your car help you keep your car problem-free?

Let’s start by looking at what your car goes through just driving you around town each day. In the winter, mag chloride and road salts are dumped onto the road before any threatening storm. Mix in a little moisture, and they stick like glue all over your car. But don’t think it gets better in the summer. Bird droppings, sap, pollen, bug splats, and more find a way to get into every nook and cranny of your vehicle.

All of that can corrode the paint, damage the undercarriage of your car, and destroy the integrity of many of your vehicle’s safety systems.

Luckily, the solution is easy. Wash your car at least twice per month to get all the muck away from the essential parts and systems. This will keep it shining and looking as good as possible for wherever the road takes you. And let’s be honest, it just feels better driving a nice looking car, doesn’t it?

Check fluids

Your car has a number of fluids in it to keep it running its best. Some you know well – hello, gasoline. If your car has gas, it goes. Without it, it stops. We’re all naturally trained to watch the tiny gauge on our dashboards, driving into a gas station before the needle touches the “E”.

But cars don’t run on gasoline alone. There are many other fluids used to ensure a vehicle is operating correctly. According to a Popular Mechanics article, there are six fluids you should check on a regular basis:

Motor Oil – your engine is the hub, controlling every aspect of your car. Motor oil keeps everything lubricated and working smoothly.

Coolant – your vehicle builds up a lot of heat as it operates. Coolant helps absorb heat produced by the engine, and moves it through the radiator to keep your car from overheating.

Power Steering Fluid – want to keep your steering wheel turning effortlessly? Ensure your power steering fluid is topped up and that no leaks are in the system.

Brake Fluid – without brake fluid, when you press down on the brake pedal, your car won’t stop the way it should. While this isn’t a fluid you top off like motor oil, it is something a mechanic should check if you have trouble braking.

Transmission fluid – it has a similar purpose as oil, designed to cool the parts inside your transmission.

Windshield washer fluid – this is mandatory fluid here in Colorado to ensure you see where you’re driving.

Maintain your tires

Tires aren’t something you put on and forget. They keep your car rolling in all kinds of conditions. But as they operate in freezing temperatures and triple-digit weather, they change. They’ll lose pressure even if they’re operating correctly. That’s why it’s mandatory that you check tire pressure regularly.

Do you know how much air to put into your tires? Don’t look at your tires for the answer. Instead, check your owner’s manual or search for a sticker on the driver’s door jamb. You’ll find advice on what the proper tire pressure levels are.

You’ll also find recommendations on rotating your tires. This ensures they wear evenly, which gives you maximum wearability out of each set of tires you buy.

Change air filter

Some of the biggest car maintenance problems develop because car owners avoid doing the simplest of things. Changing out your air filter is one of them.

It can be done in a matter of seconds, but the implications can be long-lasting. An air filter is designed to keep harmful dirt and debris away from your engine. By changing it out regularly, you’re keeping the engine’s performance at its best. You’re also ensuring the engine works properly, and fuel economy is maximized.

Often, an air filter is changed out during a normal oil change. Ask to ensure yours is changed.

Check belts and hoses

Belts and hoses are in constant motion, helping keep all of your systems operating the way they should. As they wear, they put you at more risk of being stranded as they crack, leak, or break.

For example, if a serpentine belt breaks, it can cause failure in a number of your car’s systems, including power steering or your air conditioning. If a radiator hose develops a leak, it can lose coolant that is necessary to keep your engine from overheating.

The cost of a new belt or hose is far less than the damage caused by having them fail. It can be the difference between a simple car maintenance item, or a full-blown failure with an extensive repair bill.

What’s the easiest way to tell if your car has a problem with belts and hoses? Pay attention to your car. Does it make funny sounds? Does your car act differently? Do you smell something odd? Pay attention and consult a mechanic as needed.

With just a little effort, your car will continue to run well from the moment you drive it home for the first time. It’ll keep you and your family safe as you move through your busy days. If you have a question about your vehicle, just ask. 

Question on Your Drive Shaft

by

Question:  My name is Doug and a few years ago, I was driving my 1985 powder blue Dodge Ram Charger that had about 80,000 miles on it at that time.  I was going up a hill and heard a noise like a tin can rolling down the road.  I looked back and saw my drive shaft bouncing down the hill.  I put it in four-wheel drive and drove to my mechanic to get it fixed.  What could I have done to prevent that?

Answer:  Wow, that’s quite a story.  Doug was very fortunate that his vehicle had a part-time four-wheel drive system that would allow him to get home without a rear drive shaft.

This case of “the missing drive shaft” highlights the need for regular inspections.  Most of us are familiar with recommendations for preventative maintenance services like oil changes and coolant replacement.  What may not be as familiar to you is that there are also recommendations for inspections at various intervals.

By the time a vehicle gets 80,000 miles on it,  like Doug had on his vehicle, the owner’s manual would have called for inspections of things like the suspension, brakes, and the drive line.  Chances are that such an inspection would have revealed early signs of a worn u-joint and Doug could have had it fixed before his drive shaft went rattling down the road.

Ask your service adviser about the inspections your vehicle might need so something like this doesn’t happen to you.

Car Maintenance An Auto Mechanic Would Love – Take Care Of Your Vehicle

by

Owning an automobile is no longer optional. Here across the Front Range, it would be difficult to live without a car. How would you take the kids to school? How would you run errands? How would you get the family up into the hills for a day of skiing?

A car is something you depend on to get you where you’re going, every day of the week.

The newer the vehicle, the more reliable it is. But even from the moment you drive it off the showroom floor, things start to wear and break down. Every mile allows belts to wear out, tires to wear down, fluids to run low. If you don’t pay attention to the changes in your car’s normal patterns, you’re likely to miss when it starts to tell you things are changing. Action is needed. Or problems will quickly begin materializing.Car Maintenance An Auto Mechanic Would Love - Take Care Of Your Vehicle

Car maintenance and repair

Why is car maintenance and repair such an important thing? There are a lot of reasons why you should keep your vehicle in top shape. These are just a few of the many reasons why you should put “taking care of your car” at the top of your to-do list.

Improves safety

While basic car maintenance might not directly stop vehicle accidents from occurring, it can be a contributing factor in many situations. If your tires are bald, for example, you’re more likely to hydroplane and slide in wet or icy road conditions. By keeping all critical components of your car in top shape, your vehicle will handle better, and is more likely to react quickly when you tap on the brake pedal or turn your steering wheel.

Increases reliability

Certain parts of a vehicle will wear more than others. The windshield washer fluid reservoir can only hold a certain amount of fluid. The brake pads will only withstand a certain amount of pressure. Tires will only provide a certain amount of wear before the tread disappears. If you make a conscious decision to check and replace parts before they wear down, your car is less likely to break down when you least expect it.

Decreases your repair expenses

If you don’t put gas into your car before the tank empties, it’ll come to a complete stop, and you’ll be stuck. Every car owner understands that, so they watch the gas gauge and pull into a station before the needle hits the E marker. The rest of your car works in a similar manner, though it’s easier to ignore the warning signs. If you don’t replace motor oil, your engine won’t work at 100 percent efficiency. But it still keeps trying, and that’s when things start happening. Other parts overcompensate to make up the difference. And pretty soon that simple oil change turns into a much bigger problem. If you stick with a car maintenance checklist and you perform routine maintenance on a regular basis, your vehicle will be there when you need it.

Has a higher resale value

When people don’t take care of their car, it shows. When it’s neglected, it may have layers of dirt, parts missing, even sounds you know aren’t good for the car. When you perform car maintenance regularly, even a car that is several years old can appear to be brand new. It shines. It appears to be well cared for. Even when you climb inside or pop the hood, you can see the previous owner didn’t let things fester. And people are willing to pay a higher price, knowing they are purchasing a car that will be reliable from the moment they drive it home.

Is better for the environment

Unless you drive an electric car, you know cars that operate using fossil fuels aren’t running with the cleanest energy source. But if you operate your vehicle the way it was designed, it is operating efficiently. When you make sure your engine has the right amount of oil, for example, it’s not leaking fluid that can absorb into the ground, or sending off emissions that are bad for the environment. It runs as clean as it possibly can.

Checklist for car maintenance

Are you convinced regular car maintenance is the right thing to do?

Are you wondering how to fit regular car maintenance into your already busy schedule? That’s the easy part. With this simple checklist, you can ensure your vehicle is operating as it should for as long as you own the car. Here’s what to do.

Keep your owner’s manual handy

We get it; your owner’s manual isn’t exactly exciting reading. In fact, it can be downright intimidating. Depending on your vehicle, it can be hundreds of pages of detailed information describing every aspect of your car. But it does contain information that can help you keep your car safe and working its best. Take note of the maintenance section. It’ll give you guidelines for the things you need most, such as how often you should change out motor oil and filters, tire rotation, belts, hoses, and more.

Schedule your oil changes

From the beginning, get in the habit of scheduling regular oil changes. It’s the lifeblood of your vehicle. Without it, parts wouldn’t stay lubricated, gears wouldn’t work the way they should, and parts would wear out faster than intended. Pay attention to the manufacturer’s guidelines – what’s the best oil for your make and model? Again, refer to your owner’s manual for guidelines, and trust a reputable mechanic to ensure it’s performed in the proper manner.

Keep an eye on your tires

One of the most important car parts to help keep you on the road is the tires. If they aren’t filled properly, are worn down, or not well cared for, they can blow and increase the chances of having a major accident. Your owner’s manual will tell you proper guidelines for tire pressure. Once a month, check tire pressure and ensure that each tire is filled to proper capacity.

Belts, hoses, and fluids

Especially in the winter, when you use your windshield wipers regularly to clear away moisture and muck, you might run out of windshield wiper fluid enough you even keep a bottle in your car. When you pop the hood to fill the reservoir, take a quick peek at the hoses and belts. Does anything look out of place? You don’t have to be an auto mechanic to tell when something is wrong. If you do this regularly, you’ll recognize when everything is in its proper place, and more importantly, when something doesn’t look quite right.

Car maintenance near me

Regular car maintenance doesn’t have to be difficult or even take a lot of time. Regularity is the key.

When you have a reliable auto mechanic nearby who you can trust to tell you like it is, you’ll have a way to keep your car working in a dependable way.

No matter if you have a problem that needs to be fixed, or just want a second pair of eyes to ensure your vehicle is at its best, stop by today. We’ll help you keep your car in its best condition, so you’ll have one less thing to worry about during your busy days.

Why Is My Steering Wheel Hard To Turn?

by

Imagine cruising down the highway on your way to work. You put on your turn signal, hoping to merge onto the exit, and turn left or right to reach your final destination. The only trouble is your steering wheel isn’t cooperating. You tug at it, push it, try to control it with all your might. Why is your steering wheel hard to turn?

When your steering system fails, it impacts the performance and safety of your vehicle. If you can’t move spur of the moment, adjust no matter what happens on the road in front of you, you’re putting your life, the lives of the other occupants in your car, and all those around you at risk.

At the first sign of trouble, act quickly.Why Is My Steering Wheel Hard To Turn?

Getting to the root cause of your steering wheel problems

The steering wheel problem mentioned above isn’t uncommon. If you drive, at some point you’ll find yourself in a situation where you have trouble controlling the steering of your vehicle. If it suddenly becomes stiff and hard to turn, your steering column didn’t suddenly break. Instead, it’s quite possibly an easy fix you can troubleshoot and repair quickly.

Most newer cars today use what’s called rack and pinion steering. It contains two main parts: the pump, and the rack and pinion unit.

The pump provides power steering fluid to the rack and pinion unit. As a driver moves the steering wheel, the power steering control valve allows fluid to flow into the piston, giving the driver the ability to turn the wheel. As the wheel turns, the pinion moves against the rack, pushing it in the direction the driver wishes to go.

Before power steering, this gear shifting and movement took more power from the driver. It was a more strenuous ride, as more of the power relied on the driver controlling the turns. With power steering, the process has improved, making it easy for a driver to control steering in all kinds of conditions. If you have to make a split-second decision, it’s nice to know that your vehicle gives you the option to react quickly.

When your steering wheel is hard to turn, there are a number of things that could be wrong.

Your power steering fluid is low

Your car is filled with different types of fluids to keep it operating the way it should. Power steering fluid provides fluidity to the rack and pinion gears. Without it, it will be difficult to move. If your car is low on power steering fluid, refilling it can be a temporary fix. If it’s low, you’ll have to get to the root cause of why it’s disappearing out of the power steering system. There’s a good chance one of the hoses or connectors is loose, cracked, or broken, allowing the fluid to disappear out of the system.

It might not be your steering wheel at all

Cars are finely tuned machines that work well when all systems are operating correctly. When something goes wrong, all systems are thrown off balance. If you’re having trouble steering your car, take notice of when it occurs and what it does to your vehicle. It might not be your steering system at all. In some cases, if your tires aren’t filled to their proper levels, it can make the steering process more difficult. When was the last time you had your tire pressure checked? Make sure they are inflated according to your car’s make and model guidelines.

It could be hoses, belts, or connectors

Like every system in your car, the steering system is made up of many different parts. It has hoses and belts that connect pieces together, connectors that hold everything in place. If any one of these fails, your power steering system will act up, making your steering wheel difficult to turn.

Between the steering column and the rack and pinion shaft is a thick rubber piece that absorbs the shocks of the road. This rubber can wear out over time.

The steering wheel and the rack and pinion shaft sit at angles to each other. Couplers are used to keep these angles in perfect alignment. Of course, anything created to work at an angle has the potential to go out of alignment if the angle isn’t correct. If this coupler fails, it can throw the entire system out of whack.

The power steering system is controlled by two central hoses. Both are attached to the rack and pinion and the power steering pump through brass fittings, secured by hose clamps. This system is constantly under pressure by carrying power steering fluid to the appropriate parts, and by the movement of the vehicle against the road.

It might be a bad steering rack

The rack is connected to your power steering system through a series of shafts and u-joints. Even under normal driving conditions, the rack will wear down over time. If your steering wheel is stiff from the moment you turn on your vehicle, it’s most likely a problem with the steering rack. The wheel will gradually loosen as you drive and it heats up, giving the lubricant a chance to move in and start to work. You can keep driving with this condition for a while, but keep in mind the problem only escalates as the steering rack continues to deteriorate.

It can also be a power steering pump failure

Just like other pieces of equipment in your car, your power steering pump is designed to last for thousands of miles. It has a major role in creating the right amount of pressure in the power steering system. When the pump comes under pressure, is damaged, or simply wears out, it won’t do its job the way it should. When it reaches the point of failure, it won’t cause the system to stop working. But it does start to give signs it’s time for replacement. The steering point often makes noise to signal it’s time for replacement. Your steering wheel will become harder and harder to turn. If you notice these changes in your vehicle, it’s time to have it serviced and replaced.

What’s the easiest way to ensure your car is always running the way it should? It starts with a regular maintenance schedule. Check all fluids at regular intervals. Bring your car in for diagnosis whenever you think your car might have a problem. If your steering wheel is hard to turn, it’s signaling you it needs attention. Stay safe, and let’s solve the problem to get you back on the road again.

Guide to Battery Replacement

by

Most folks know that car batteries wear out just like any other battery and need to be replaced.  There are a couple things drivers should know and keep in mind as a guide to battery replacement.  One is cold cranking amps and the other is reserve capacity.

We’ll start with cold cranking amps.  Think of this as the power output used to start a cold engine.  The number of cold cranking amps you need depends on your vehicle and where you live, or specifically, how cold it is where you live.  Two factors to consider are that the colder an engine is, the more power it takes to turn the engine over to get it started.  It has all that cold, sluggish oil to contend against.  The second factor is the chemical reaction in the battery that creates electrical energy is less efficient in the cold.

So the colder the weather gets, the more power is needed, but is unavailable.  So if you live where it’s cold, you need a battery with more cold cranking amps than you would where it’s moderate or hot.  You should always get at least as many cold cranking amps as are recommended but you may want to upgrade if you live where it gets really cold.

An important guide:  Batteries may also list the Cranking Amps-CA-number.  It is the Cold Cranking Amps – or CCA – that is the number you’re interested in here.  CCA is the number to use in your comparisons when you’re shopping for a battery replacement.

With all this talk of cold temperatures, it’s also important for drivers to note that heat is the real enemy of long battery life.  In other words, the damage that’s done over the summer months shows up with the increased demands on the battery when the weather turns cold.

Now let’s talk about reserve capacity:  It’s the measurement of the number of minutes of reserve power the battery has at a given load.  The number is more important these days because of parasitic drain.  Parasitic drain is the battery energy that’s used when the key is off.  This is the power drawn by the security system, the remote start system, and even the power the computers require to maintain their memory.

Reserves are also needed when you make very short trips, you’re not driving long enough for the vehicle battery to recover the energy it used just to start the engine.

A basic guide to battery replacement is to go with the recommended minimum unless you believe you need more and want to upgrade.  Talk to your friendly and knowledgeable pros about your options.

What To Do When Your Power Steering Goes Out

by

Power steering on today’s automobiles is something most of us take for granted. But if you’ve ever had it disappear, you’ll appreciate it a little bit more.

It can be kind of scary, especially here along the Front Range. You’re driving. Heading to the office, or maybe off for a weekend in the mountains. You’re singing along with the radio, talking with the family, and suddenly it’s very difficult to turn the steering wheel in your car. What do you do when your power steering goes out?

Depending on what’s wrong determines the right course of action. Not all power steering problems require extensive repair work. But like other car repair issues, quick action can often save you time and money down the road.
What To Do When Your Power Steering Goes Out
Understanding Power Steering Technology

Power steering isn’t new technology. In fact, it was put in place as the first automobiles started flowing off the production line.

Hydraulic steering uses a pump to supply pressure. Driver control is authorized by use of rack and pinion. Fluid pressure is created within the pump, and pushed against a piston. As the wheel turns, pressure builds and flows, causing the piston to move. This piston is also attached to the steering mechanism, and with the air of hydraulic pressure, the steering wheel is moved and controlled by whoever is driving.

It all comes down to a highly sensitive valve system. When the steering wheel is straight, the steering valve is at rest. But as you turn it, fluid begins to flow around the valves, through the reservoir, and into the cylinder. The fluid moves and flows to different pressure chambers, depending on the direction you turn the wheel to control the gears. When the steering wheel is released, it returns to its neutral position.

When The Power Steering Goes Out

If there is a problem with any part of this hydraulic system, you’ll know it. Even a slight turn of the steering wheel will exert pressure, be more stubborn and stiff, and require more power to create the action of turning. If you drive for any distance, it can actually leave you a little sore. It also begs the question: what’s wrong?

One of the simplest solutions is power steering fluid is low. This could be caused by a leak somewhere in the system. It could be caused by a lack of maintenance over the years, and your fluid has simply run out over time.

It might be due to contamination within the power steering fluid. As you drive your car, parts wear down and start breaking off. These tiny pieces can end up in the power steering fluid and corrode the functionality of the power steering fluid.

A more serious problem could be that the pump itself is failing. While this isn’t a common problem, it does happen from time to time. The best way to prevent any of this and stay on top of a potential problem is to be proactive from the start. If you take care of your system, provide regular servicing, this shouldn’t be an issue.

You can also watch for a potential leak by paying attention to what’s underneath your car. If you leave it set for any length of time, check for fluid. If you see a pink or amber puddle, it might be steering fluid. You can add power steering fluid yourself, or get it into our shop quickly so we can evaluate your entire system and ensure everything is working up to par.

Can It Be Something More?

Keep in mind that your car is put together with thousands of pieces all interlocked together, relying on each other to make sure everything works as it should. When one thing goes wrong, it can create a snowball effect, causing more pieces to go bad.

Every movement your car makes has enough force to impact different pieces. A shimmy or a shake is absorbed by the steering gear. If tires are low or out of balance, it can increase the likelihood of a recurring shimmy every time you drive. If the force is strong enough, it will damage bearings and impact the gears. This gives the drive system free play, meaning it starts the process of making steering difficult to control. It’s not an all-or-nothing problem. It occurs gradually over time.

Many drivers are misled to thinking you can control this shimmy by adjusting the nuts on the top of the steering gear. You can’t. Turning this will not eliminate shimmy, and may actually do more damage to the gears then leaving it alone. This can bind the gears together, essentially making the problem even worse.

It may also be from worn out steering valves. If power steering seems fine when you first turn your car on, and becomes increasingly more difficult as you drive, it may be the steering valves. A reputable repair shop can help make the diagnosis and fix the problem.

What If Your Power Steering Goes Out While You’re Driving?

What if you miss all the warning signs and the power steering goes out while you’re driving?

Don’t panic. The important thing is to slow the car down and remove yourself from traffic. Turn on your blinkers to signal moving over to the side of the road. You can turn on your hazards as well, further indicating to those around you that you have a problem.

Don’t stomp on the brakes. Depending on how fast the car is going, this could send you into a tailspin. And without the ability to steer, this could put you in a hazardous situation. Brake slowly and move over to the side.

Once you get the car stopped, turn the car off and on again. Test the wheel, can you move it easier? Sometimes the act of turning the car off can reset your system. This may give you the chance to move your car from traffic and get it in to our shop as quickly as you can. If you still notice problems, your best bet is to call for a tow truck.

Keep Your Power Steering In Good Health

Like all systems, your best bet is to keep your power steering system in the best shape possible to avoid potential problems when you least expect it. If you can’t remember the last time your power steering fluid was changed, maybe now is the time.

Use our coupon for a power steering flush. We’ll ensure everything is working the way it should, to keep you and your family safe every time you get into your car and head out into traffic.

Change Your Oil, Drivers!

by

As engine technology advances, recommended oil change intervals have gotten longer.  High quality oil in a well-engineered engine has led to extended intervals.

Here’s the problem:  With longer oil change intervals, it’s extremely important to follow them closely.  Back in the day of 3 months or 3,000 miles, if you went an extra month or an extra thousand miles, your oil was still fresh enough that it didn’t have time to build up much sludge.

But if your recommended interval is 6,500 miles and you go over another thousand, you’re getting into heavy sludge territory.  This can cause big problems.

You absolutely need to follow mileage intervals on changing your oil very closely.  And don’t forget your severe service schedule.  If you do a lot of stop and go driving, short trips, drive in dusty or polluted conditions, hot or cold weather, or haul heavy loads, you’re driving in severe service conditions.  Is your driving closer to the regular schedule or the severe service schedule?  It’s your call as the driver to decide when to change your oil to protect your engine.

If your car came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil.  If you use conventional oil, you shouldn’t be using the synthetic oil interval – you need to shorten it.

Service advisers often report that when they talk to a driver with 200,000 miles or more on their vehicle, the vehicle owner will say their secret is changing the oil on time.  Please don’t skip an oil change.  Once sludge has started to build up, it’s tough to get it out.  So don’t let that happen to you!  Change your oil, drivers!

Car Doesn’t Start? Is It The Battery or the Alternator?

by

Nothing is worse than going out to your car, turning the key, and nothing happens. You hear a slight click-click noise, but nothing happens. And if you try it again and again, even that stops.

You had plans! Now what?

If your car doesn’t start, it’s a sign that something is wrong with your starting system. It could be caused by several things, including:

  • A dying or dead battery
  • A bad alternator
  • Loose or corroded connection cables

But first, before we determine where your problem lies, it’s important to understand the differences between the alternator and the battery, and what they each do.Car Doesn’t Start? Is It The Battery or the Alternator?

The Alternator

Think of your car’s alternator as the power generator that supplies energy throughout the vehicle’s charging system. All vehicles using an internal combustion engine use an alternator.

When the engine is running, the alternator kicks into gear, charging the battery and supplying energy throughout the electrical system.

It’s bolted to the engine and is driven by a serpentine belt.

The Battery

Your car’s battery is what keeps it running. It stores energy and transforms it into power as needed.

Yet a car battery is different than other batteries you use around your home, such as in a watch or your television remote. With a car battery, the greatest thrust of power is at the time you turn the key. It needs maximum current for a short period of time to jolt the vehicle into action.

That’s known as an SLI battery. SLI stands for starting, lighting, and ignition. It sends short bursts of energy to power your lights and other accessories. But one the engine comes to life, the power to keep the car running is supplied by the alternator.

If your car is still relatively new, most vehicles are equipped with a generic SLI battery. They aren’t designed for optimum use, or for long life.

My Car Doesn’t Start – Why?

When the alternator starts to fail, the battery jumps into action and starts picking up the slack. No matter how good your car’s battery is, it isn’t designed for this level of use. It will eventually wear down, and leave you stranded somewhere along your journey.

Car batteries are not intended for long term power supply. When your car doesn’t start, it’s easy to assume it’s the battery’s fault. But there’s an easy way to determine where the problem really lies.

Jumpstart your car with a set of jumper cables. Remove them as quickly as possible once your car comes to life. Then wait.

If the car continues to run, it was likely a problem with the battery.

If the car soon dies, you’ve pinpointed it’s a problem with your alternator.

Even if you get the battery running again, keep in mind that this might be a temporary thing. Something caused the car to stop working in the first place. Even a jump start might not keep it running for very long.

You can test the battery with a voltmeter to determine its life.

What Else Should You Watch For?

Because the alternator is critical to keeping your car’s electrical system working the way it should, any mechanical problem can be a sign that something is going on with the alternator.

In newer cars, everything is computerized. You’ll have warning lights for just about anything mechanical in the system. If a problem exists with your alternator, you’ll most likely see a warning light shaped like a battery flip on. Some may also blink “ALT” or “GEN” instead. This light is telling you the car has a voltage problem. It’s in the early stages of failure.

Most alternators require 13 to 14 volts to operate your vehicle effectively. Too little, and your car will have problems working. Too much, and it will corrode the system.

You might notice other things not working as well as they once did. Since the alternator supplies electrical current, you might notice your headlights dimming, not as bright as they once were. You might notice your dash lights begin to fade. Maybe your tachometer stops working. Or the heated seats turn off before its time.

This is your car’s way of compensating for a problem. It’s putting energy to the one place that matters most – keeping your car running while warning you to pull over and stop the car.

It might also be broken or loose connections.

Electricity from your alternator runs through a series of cables and wires. If there are any problems with these cables, wires, or connections, it can stop the energy from moving from one point to another. This symptom is often accompanied by a burning smell as well. If too much power is generated to one spot, it will produce higher voltage, in effect “cooking” one area of the system. It gives off a distinct smell that warns you of potential problems.

We’ve also had cars come in with starting problems, only to discover it’s a problem under the hood. If a belt brakes, it can hang off the engine block, flapping around as you operate your vehicle. It may be missing altogether. Broken or loose belts are pretty easy to spot; open up the hood and take a peek. Even if you aren’t skilled in auto mechanics, you can usually spot a potential problem.

Because every car is different, it’s best to get in tune with your car. Watch – listen – smell – those should be things you do every time you’re in your car.

Watch for signs that something is wrong. Do you see lights on the dashboard? Do you see things that aren’t working the way they once did? Is something harder to turn? Or do certain functions disappear?

Listen for any new noise that wasn’t there before. Pay attention to clinks, buzzes, hisses, and bangs. If there isn’t a logical explanation for it, it might be your car’s way of telling you something is wrong.

Likewise, a new smell is telling you something isn’t working the way it should. You have something spilling, overflowing, leaking, or disappearing. And when each piece of your car doesn’t have the proper tools to do its job, it’s going to find a way to do it anyway it can.

Have you noticed something new with your car? Don’t let it go. At the first sign of trouble, bring your car in and let’s diagnose the problem. If could be the difference between a minor repair and a major overhaul.

Serpentine Belt Replacement

by

Your serpentine belt is a long belt that’s driven by your engine.  It winds around several accessories that power important automotive systems.  Let’s go over them.

  • First, the serpentine belt drives your air conditioning system.
  • Next, the belt powers the alternator.
  • The serpentine belt may also run the pumps for both the power steering and power brakes.  In some vehicles, power steering may have an electric drive and power brakes can be vacuum driven.
  • On many vehicles, the serpentine belt powers the water pump ( on some cars, the water pump is powered by the timing belt).

Your service technician can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and also measure the amount of belt material to make sure there is enough.

There’s a special, spring-loaded pulley attached to the engine called the tensioner pulley and sometimes an extra pulley called the idler pulley.  Their job is to make sure there’s a constant tension on the serpentine belt so that it doesn’t slip.  The spring can become worn and no longer provide the necessary pressure to keep the belt tight.  That’s why it’s often recommended that the tensioner, and the idler pulley, if so equipped, be replaced at the same time as the serpentine belt.

All in all, the serpentine belt’s an important part for the function of your vehicle and it’s not as expensive to replace as you might think.  So it’s good to do your serpentine belt replacement before it fails.
